Echocardiographic Features of Longevity: A Cross-Sectional Study of Centenarians.

ABSTRACT

BACKGROUND: Centenarians represent an under-studied population within cardiovascular medicine. This study aimed to describe the echocardiographic characteristics of a cohort of centenarians at a tertiary referral center. MATERIALS AND METHODS: The institutional Echocardiography database was retrospectively reviewed and identified 100 consecutive centenarians referred for transthoracic echocardiography between January 2009 and December 2020. Cardiac chamber quantification, diastology, and valvular heart disease were assessed according to the American Society of Echocardiography guidelines. Independent t-tests and Mann-Whitney U-tests compared data between males and females. RESULTS: The mean age was 101.5 ± 1.7 years, 78% were female, and the most common co-morbidities were hypertension (77%), coronary artery disease (46%), and congestive heart failure (42%). The mean left ventricular (LV) ejection fraction measured 56.9 ± 11.3% (females vs males, 58.4 ± 9.8 vs 51.6 ± 14.6%, p = 0.01). Males had larger LV end-diastolic (2.8 ± 0.6 vs 2.5 ± 0.5, p = 0.03) and end-systolic diameter (1.9 ± 0.6 vs 1.6 ± 0.4, p = 0.001) indices; a smaller relative wall thickness (0.54 ± 0.18 vs 0.69 ± 0.36, p = 0.06); and a lower E/e' ratio (13.3 [10.3-19.6] vs 17.3 [13.2-23], p = 0.05), when compared with females. The prevalence of severe valvular lesions was 13.5%, and similar between genders. However, in patients with aortic stenosis, the transaortic pressure gradients were significantly higher in females (mean gradient 32.0 ± 17.7 vs 18.7 ± 9.2 mmHg, p = 0.04). CONCLUSIONS: The present study on centenarians affords a cross-sectional evaluation of cardiac structure and function in a growing population, and highlights important differences between male and female patients.
